Hello

I'll check performance and CPU charge of program.

Usually I use this
$OOTIONS TIME.MILLISECONDS
T=SYSTEM(12)
DO...
PRINT SYSTEM(12)-T

Its about e execution time but I'll identify the CPU charge... To use efficient instructions because the program run for large qty if users. 

May I use SYSTEM(9) instead system 12?

Thanks for any suggestions.

SYSTEM(9) returns the millisecond CPU count charged to your process. This is the value you want. SYSTEM(12) only returns the current wall-clock (elapsed) time.

The Hitchhiker's Guide to the UniVerse, Part 1, describes how to use this for your purposes. The Hitchhiker's Guide to the UniVerse describes a performance unit test application that I wrote to measure the cost of BASIC statements and how varying data might affect performance.
